On 21 July 2025, Dutch offshore installation firm Van Oord has announced that it has ordered two next-generation subsea rock installation vessels, which will built by CIMC Raffles Offshore Engineering Pte Ltd (CIMC Raffles) in China.
Capable of operating on methanol and with a focus on innovation and automation, the two vessels will be cost price winners in the market. The first vessel is expected to enter the market in 2028, with a second vessel expected to follow within one year.
The new vessels will be equipped with a substantial loading capacity of 35,000 tonnes, will be capable of handling large rock sizes, and feature a DP-2 dynamic positioning system. This advanced system will enable the vessels to maintain precise positioning despite challenging conditions such as waves, wind and currents. These features will make the vessels ideal for long-distance projects, as they will minimise round trips, reducing emissions and costs per installed rock volume.
The sustainable design of the vessels includes multi-fuel engines (biofuel and methanol), a DC-grid with large battery storage capacity, and an energy-efficient hull design and rock handling system. These technologies enable a reduction in CO₂ emissions, supporting Van Oord’s net-zero strategy.
Subsea Rock Installation, pioneered by Van Oord since the 1970s, is vital for protecting and stabilising offshore energy assets. With a track record in efficient and innovative flexible fallpipe vessels, Van Oord is a market leader in seabed intervention.
Van Oord currently operates three Subsea Rock Installation vessels: Stornes, Nordnes and Bravenes. The new vessels will build on this proven platform, offering key upgrades to meet future offshore challenges. The vessels will be constructed by Yantai CIMC Raffles Offshore in China.
